Social knowledge graph for collective learning

Abstract

The invention describes a method for users to create, edit and share heterogeneous graphs representing linked knowledge and information, where a graph is a concept in computer science able to represent complex linked data.

I claim: 
     
         1 . A method for organizing, navigating and visualizing information, comprising:
 (a) a user graph containing a plurality of nodes and edges, where nodes and edges contains information such as text, image, hyperlink and the information of the user;   (b) displaying a part of said user's graph with a focus of a specific node, and the said part of the said user's graph is retrieved from a client system or a server system based on said focus;   (c) Said focus can be switched with signals from input devices like keyboard, mouse and touchscreen;   (d) a node of one user's graph can be linked to another node of a different user's graph.   
     
     
         2 . A method for organizing, navigating and visualizing information, comprising:
 (a) a user graph containing a plurality of nodes and edges, where nodes and edges display information such as text, image, hyperlink and the identity of the user;   (b) displaying a part of said user's graph with a focus of a specific node, and the said part of the said user's graph is retrieved based on the condition whether the said focus node and its neighbour nodes are connected by edges;   (c) Said focus can be switched from one node to another node by signals from input devices like keyboard, mouse and touchscreen;   (d) a node of one user's graph can be linked to another node of a different user's graph.   
     
     
         3 . A system for editing, displaying and sharing of information, comprising:
 (a) an edit system for users to create user graphs via input dialogs, where a plurality of nodes and edges with information such as text, image, hyperlink and the identity of the user can be input;   (b) a display system consisting of showing a focus of a specific node and a part of said user's graph, and the said part of the said user's graph is retrieved based on the relationship of said focus node and its neighbour nodes, and if a node of one user's graph is linked to another node of a different user's graph, showing an identification of the user of the foreign node where said identification method includes user name and unique user id;   (c) an interaction system that said focus can be switched from one node to another node by signals from a user's input devices like keyboard, mouse and touchscreen;   (d) a data storage system that allows nodes of one user's graph to be linked to another node of a different user's graph.
